Why Energy Efficiency Matters for Homeowners
In yesteryears, the concept of energy efficiency was still in a developmental stage in terms of public opinion. However, after stark climate shifts and a surge in energy costs, it’s very much part of the public conversation, rightly so. Before we tackle deeper information, let’s set the scene for how current and aspirational homeowners can include energy efficiency when scouting.
If your home uses and retains energy well, you also do your wallet and purse a favour. Energy-efficient homes typically have lower monthly utility bills, even though the upfront investment will cost you. However, this should balance itself out within a year or two. An example is improving a home’s energy efficiency to an EPC rating of C, which could save UK households up to £951 annually, with potential savings across the country reaching £24 billion by 2030.
Do you need more financial reasons to consider energy efficiency? High EPC ratings often attract buyers and may command higher sale prices. Properties rated A or B can sell for around 3.4% more than D-rated properties, while low-rated properties (F or G) often sell for 7.4% less. Upgrading a home from an EPC rating of F or G to a C can increase its market value by up to 19.6%, adding substantial financial benefit for homeowners.
Energy-efficient homes are better insulated, maintain stable indoor temperatures, reduce drafts, and stay warm in winter and cool in summer, making them more comfortable year-round. Your home will also consume less energy, lowering its carbon footprint and contributing to a greener, more sustainable environment.
How Energy Efficiency is Measured in the UK
Now that we have a general overview of energy efficiency, how is it measured? This is a necessary question because we must ground the concept with data. Our focus now shifts to the range of measurement indicators, tools, and data sets that comprise how we calculate energy efficiency.
Energy Performance Certificates (EPCs)
We begin with the general standard—the energy performance certificate (EPC). EPCs are mandatory certificates that grade a property’s energy efficiency from A (most efficient) to G (least efficient). So, we’re aiming to become the A student for the environment.
EPCs are essential for buyers and renters. They offer a snapshot of a home’s energy performance, estimated energy costs, and potential improvements to increase efficiency. It’s also worth erring on the side of caution if the seller, agent or landlord can’t provide one.
Key Metrics in EPCs
- Insulation Quality: This assesses the effectiveness of wall and roof insulation in conserving heat. Remember that some new builds highlight insulation, but this doesn’t always mean high quality.
- Window Efficiency: This rating system rates windows based on their ability to prevent heat loss. Double or triple glazing can improve scores, but only if their heat retention matches the glazing grade.
- Heating Systems: Evaluate the efficiency of heating systems and hot water controls, including thermostats and modern boilers. This is particularly necessary for older buildings with equally aged systems because the replacement costs are essential to know.
- Lighting Efficiency: This part considers the proportion of energy-saving light bulbs in the property, contributing to lower energy consumption. Luckily, lighting efficiency is the least costly aspect to upgrade.
Property Surveys
Professional energy assessments often involve on-site property surveys that assess current energy efficiency and recommend upgrades. Requesting a comprehensive survey report should be one of your primary questions for sellers and estate agents.
These surveys can highlight key improvement areas, such as adding insulation, upgrading heating systems, or improving window glazing. However, you must read the survey and check what it covers—not all reports are created equal.
Standard Assessment Procedure (SAP)
SAP is the UK government’s official system for evaluating the energy performance of residential buildings. The scores range from A (92 and above) to G (1-20), providing a clear benchmark for energy efficiency, including grey areas and potential problems.
Key SAP Metrics
- Energy Use per Floor Area: This measure measures energy use relative to property size, aiding in accurate assessment and potential issues. Further investigation is needed if a flat performs worse than a detached house.
- Annual Energy Costs: This estimates yearly energy expenses, helping buyers understand long-term financial commitments and whether they fit their budget.
- CO2 Emissions: Everything, including us, has a carbon footprint, calculated as the carbon output associated with a property reflecting its environmental impact.
Environmental Impact Rating
The National Energy Efficiency Data Framework (NEED) rating, scored from 1 to 100, offers an overview of a home’s sustainability profile.
NEED gathers data on energy consumption and efficiency measures across Great Britain, linking this information with energy-saving initiatives like the Energy Company Obligation (ECO) and Home Upgrade Grant. It tracks how energy efficiency measures impact energy use, offering insights into property characteristics that influence efficiency.
Household Energy Efficiency Statistics
Government statistics, sourced from data on schemes like ECO and national housing surveys, provide household energy efficiency trends vital for broader housing plans and environmental data. This data evaluates progress in home insulation, heating upgrades, and other energy-saving measures, helping track regional improvements.
SAP is widely recognised but has faced criticism due to its modelling and assumed outcomes, especially for older properties with unique structural features. The methodology is regularly reviewed to ensure it reflects real-world performance, improving its accuracy and policy relevance.
Questions to Ask Sellers and Estate Agents
We now understand energy efficiency—it’s time to put this theory into action. This section highlights some crucial questions to prepare you for viewing properties and obtaining the finer details from sellers and estate agents.
Has the property had any recent upgrades?
Ask about recent property insulation, heating, or other efficiency upgrades, including whether this came from an assessment or survey. You’ll need to read any documentation to see if all the suggested upgrades were initiated.
Does the house or flat have an Energy Performance Certificate (EPC) Rating?
Request a copy of the property’s EPC to gauge its rating. Remember that we aim for an A (highest) and avoid a G (lowest) rating. You’ll also see recommended upgrades to improve efficiency. Be cautious if the seller or agent can’t provide an EPC, and state that they must do so before continuing any discussions.
What type and quality of insulation is in place?
Ask about the insulation in critical areas like the loft, walls, and floors. Confirm if there is cavity wall or loft insulation, and check if it has been updated recently, as this is a significant factor in energy retention.
Can you tell me about the heating and cooling systems?
Request details on the heating system’s type, age, and efficiency rating, as older systems are typically less energy-efficient. If cooling systems (like air conditioning) are present, inquire about their efficiency and usage cost. Remember that this information is part of an EPC or similar energy assessment survey, so it shouldn’t be a problem for the seller or agent to provide.
What grade of window glazing is used?
Ask if the windows are single, double or triple-glazed. Double or triple glazing significantly reduces heat loss, improving the home’s insulation and energy bills. However, the age of the glazing is a factor, and regular maintenance and resealing are necessary for long-term benefits.
Does the property have a Smart Meter?
Confirm if a smart meter is installed. This can help you monitor and manage energy usage more effectively. Smart meters provide real-time data on electricity and gas consumption, potentially lowering utility bills through better awareness.
What are the average utility costs?
Request past utility bills to gauge the typical energy costs for the property. This helps assess monthly expenses and spot any potential inefficiencies that need addressing. It also provides an insight into whether your monthly income covers the bills before you move in.
Have you had any issues with damp, drafts, or poor insulation?
Ask if there have been any issues with dampness, drafts, or noticeable cold spots in the home. Properties with poor insulation may experience these issues, impacting comfort and long-term maintenance costs. A loose roof tile can lead to rot and highlight other structural problems.
New-Builds vs. Older Properties: Energy Efficiency Pros and Cons
The general consensus is that modern properties, often referred to as new builds, have advanced or better insulation. That said, you must obtain the data behind the claim because some developers cut corners to reduce costs. You can request the same certificates and reports for new developments mentioned in this blog, and we encourage you to ask probing questions.
New-Build Advantages
- Higher EPC Ratings: New builds should receive higher Energy Performance Certificate (EPC) ratings, with the majority rated A or B. This indicates excellent energy efficiency, thanks to modern construction methods and energy-saving technologies integrated into the design. However, we reiterate our advice to request the EPC to ensure a thorough assessment exists.
- Advanced Insulation and Glazing: Depending on the home’s valuer, newer properties should include high-quality insulation and double or even triple glazing, which reduces heat loss and keeps energy costs low. Don’t assume this, though; always request the facts in writing.
- Efficient Heating Systems: Premium new builds are generally equipped with modern, energy-efficient heating systems, such as heat pumps, condensing boilers, or underfloor heating, which are more cost-effective and environmentally friendly than older systems. A word of caution—this often doesn’t filter down to budget options and affordable housing.
- Sustainability Features: Many new builds incorporate eco-friendly technology, such as solar panels, energy-efficient lighting, and even charging points for electric vehicles, enhancing both energy savings and environmental benefits.
- Lower Carbon Emissions: Compared to older properties, new builds emit significantly less CO2 per year if they install efficient heating and lower energy consumption, making them a better choice for sustainability-focused buyers.
Older Property Challenges
- Lower EPC Ratings: Many older properties have a lower EPC rating, often around D or below, indicating they are less energy efficient and may require upgrades to meet modern standards.
- Higher Energy Costs: Due to outdated insulation, inefficient heating systems, and single glazing, in some cases, older homes often lead to higher energy bills. These properties may require nearly twice the energy consumption of a new building, which translates to increased costs for heating and electricity.
- Need for Retrofitting: Common upgrades to improve efficiency include adding loft or cavity wall insulation, upgrading to double or triple glazing, and replacing old boilers. While these retrofits can significantly improve efficiency, they often come at a substantial cost and may involve considerable disruption to the home.
- Increased Carbon Footprint: Older homes emit more CO2 because they rely on less efficient energy sources and systems, making them a more prominent contributor to household emissions than newer properties.
Cost Comparisons
Initial vs Retrofitting Costs
Purchasing an energy-efficient new build may involve a higher upfront cost but saves on monthly energy bills over time. In contrast, while older properties may be less expensive to purchase initially, bringing them up to current efficiency standards can add up, especially if substantial renovations are needed. That said, this only applies to moderate to expensive new builds – affordable options often have average EPC ratings and may require similar upgrades.
Potential Savings on Upgrades
Homeowners of older properties should consider government grants or incentives to improve energy efficiency. These can help offset insulation, glazing, or heating upgrade costs. Hopefully, more government grants and initiatives follow soon to help reduce the UK’s carbon footprint.
Long-Term Potential
Feasibility of Retrofitting
With the right upgrades, many older properties can achieve energy efficiency levels that approach those of new builds. However, some homes, particularly those with unique historical architecture, may have structural limitations that make retrofitting more challenging.
Value in Retrofits
Enhancing an older property’s efficiency can increase its market value and appeal, especially as energy costs continue to rise. Retrofitting may also yield long-term savings on energy bills and improve the overall comfort and livability of the home.
Popular Upgrades for Improving Home Energy Efficiency
Now, let’s turn our attention to what energy-efficient upgrades are available. This is a quick reminder that this is an initial starting point only, so do more research before making a financial commitment.
